Washington, who's starring in "The Equalizer 2," appeared on CBS's "The Late Show with Stephen Colbert" on Thursday and discussed the role he inadvertently played in Boseman's becoming a successful actor. Washington famously paid for Boseman to study acting, long before Boseman was in the Marvel movie.

The 63-year-old actor told Colbert that when he saw Boseman and Ryan Coogler, who wrote and directed "Black Panther," at a New York screening, he jokingly asked the star when he planned on returning his money.

"I saw Ryan Coogler and Chad, and he said, 'Oh, you know, I just wanted to thank you for paying,' and I said, yeah, that's why I'm here. I'm not here to see — I liked the movie, 'Black Panther,' yeah, good, Wakanda Forever, but where's my money?'" Washington recalled.
